NOTES
ON ELECTRIC
SAFETY AND
ELECTROMAGNETIC
COMPATIBILITY.
Please, read carefully these instructions before proceeding with the
installation of the controller.
Class II instrument, rear panel mounting.
This controller has been designed with compliance to:
Regulations on electrical apparatus (appliance, systems and installations) according to the European Community directive 73/23 CEE amended by the European Comunity directive 93/68 CEE and the Regulations
on the essential protection requirements in electrical apparatus EN 610101 (IEC 1010 - 1) : 90 +A1:92 + A2:95.
Regulations on Electromagnetic Compatibility according to the
European Community directive n089/336/CEE, amended by the European
Community directive n° 92/31/CEE and the following regulations:
Regulations on RF emissions
EN50081 - 1
residential environments
EN50081 - 2
for industrial environments
Regulation on RF immunity
EN500082-2
for industrial equipment and system
It is important to understand that it’s responsibility of the installer to ensure
the compliance of the regulations on safety requirements and EMC.
This device has no user serviceable parts and requires special equipment and specialised engineers. Therefore, a repair can be hardly carried on directly by the user. For this purpose, the manufacturer provides technical assistance and the repair service for its Customers.
Please, contact your nearest Agent for further information.
All the information and warnings about safety and electromagnetic compatibility are marked with the B sign, at the side of the note.

PRECAUTIONS
B
Despite the fact that the instrument
has been designed to work in an
harsh and noisy environmental
(level IV of the industrial standard
IEC 801-4), it is recommended to
follow the following suggestions.
2.2 PRECAUTIONS AND ADVISED CONDUCTOR COURSE
B
Conduit for supply and output cables
B
A
B BB
A
B
A
All the wiring must comply with the
local regulations.
The supply wiring should be routed away from the power cables.
Avoid to use electromagnetic contactors, power Relays and high
power motors nearby.
Avoid power units nearby, especially if controlled in phase angle
Keep the low level sensor input
wires away from the power lines
and the output cables.
If this is not achievable, use shielded cables on the sensor input, with
the shield connected to earth.

Notes:
1] Make sure that the power supply
voltage is the same indicated on
the instrument.
2] Switch on the power supply only
after that all the electrical connections have been completed.
3] In accordance with the safety regulations, the power supply switch
shall bring the identification of the
relevant instrument. The power
supply switch shall be easily
accessible from the operator.
4] The instrument is protected with
a 0.2 A~ T fuse. In case of failure it is suggested to return the
instrument to the manufacturer
for repair.
5] To protect the instrument internal
circuits use:
- 2 A~ T fuses for Relay outputs
- 1 A~ T fuses for Triac outputs
6] Relay contacts are already protected with varistors.
Only in case of 24 V ~ inductive loads, use model A51-06530D7 varistors (on request)

polarity as shown
• Use always compensation cable
of the correct type for the thermocouple used
• The shield, if present, must be
connected to a proper earth.
B For Pt100 resistance

• If a 3 wires system is used, use
always cables of the same diameter (1mm2 min.) (line 20 Ω/lead
maximum resistance)
• When using a 2 wires system, use
always cables of the same diameter (1,5mm2 min.) and put a
jumper between terminals 5 and 6
C For ∆T (2x RTD Pt100) Special
A When the distance between
the controller and the sensor

AUTOMATIC
TUNING
Two tuning methods are provided:
• Initial one shoot Fuzzy-tuning
• Continuous, self learning
Adaptive Tuning
The Fuzzy-Tuning allows the calculation of the optimal PID terms parameters, monitoring the response of
the process to disturbances.
The controller provides 2 types of
“one shot” tuning algorithm, that
are selected automatically according to the process condition when
the operation is started.
Step response
This type is selected when, at the
start of the autotune operation, the
PV is far from the Setpoint of more
than 5% of the span.
This method has the big advantage
of fast calculation, with a reasonable
accuracy in the term calculation.
Natural frequency
This type is selected when the PV is
close to the SP Setpoint.
This method has the advantage of
38
a better accuracy in the term calculation with a reasonable speed
calculation.
The Fuzzy Tuning determines
automatically the best method to
use to calculate the PID term,
according the process conditions.

5 - Automatic tuning
The self-learning Adaptive Tuning
is not intrusive. It doesn’t affect the
process, at all, during the phase of
calculation of the optimal terms
parameters.
Continuous Adaptive Tuning
Perturbation
New
parameters
It is particularly suitable for controlling process whose control
characteristics change with
time or are not linear in relation
to the Setpoint values.
It doesn’t require any operation by
the user. It is simple and works fine:
it samples continuously the
process response to the various
perturbations, determining the frequency and the amplitude of the
signals. On the basis of this data
and their statistical values, stored
in the instrument, it modifies automatically the PID term parameters.
It is the ideal for all applications
where it is required to change con-
tinuously the PID terms parameters, in order to adjust the PID to
the changes of the process
dynamic conditions.

SPECIAL
FUNCTIONS
Two special functions are available:
6.1 Start-up
6.2 Timer
In order to have the above functions the product code digit E must
be 2 (see page 17)
For example: M400 3100-2000
To select these functions use the
parameter:
Timer/Start-up
operator mode
(see page 36).
t
# M
. od
A Selecting Timer or Start-up,
the Soft-start function is disabled, therefore the parameters
#st.Op and #st.tM will not
be shown. (see page 27)
6.1
START-UP FUNCTION
By means of this function it is possible to manipulate the control
output when the controller is
switched on.
To configure
Start-up
function the
parameter
“Timer/Startup operating
mode” must be set to #
1.
Three parameters are associated
to the Start-up function, they
appear on the second group.

(5.0%…100.0% min)
The Start-up function includes
three phases:
1st “Limy” - The control output is
# p.Hs
limited to the O
2nd “Hold” - The process variable
is maintained to the Start-up
Setpoint for the time fixed by
the parameter t
# h
. s
. U
.
3rd “Off” - When the t
# h
. s
. U
. time
is elapsed the process variable
is maintained to the working
Setpoint.
Whether the process variable, for
any reason (e.g. load change),
decreases at a value lower than (
#s.p.sU - 40 digits), the Start-up
function starts again from the
“Limy” phase.
When the Start-up is in Hold phase,
if the local Setpoint becomes lower
than the Start-up Setpoint or if the
operating mode changes to manual, the Start-up function passes
to the “Off” phase.
6 - Special functions
There are two possibilities:
A Start-up Setpoint # s p. s U
lower than the local Setpoint.
The “Hold” phase starts when
the process variable PV
achieves the #sp.sU (with a
tolerance of 1 digit).
B Start-up Setpoint #sp.sU
greater than or equal to the
local Setpoint.
When the process variable PV
achieves the local Setpoint (with a tolerance of 1 digit), the Start-up function
passes directly to the “Off” phase.
If, at the controller power-on, the
process variable PV is greater than
the lowest between the s
# p.sU and
the working Setpoint , the next phase
(“Hold” or “Off”) will executed instead
of the “Limy” phase.
During the
“Limy” and
“ H o l d ” phasRUN
